see text The Cyclopteridae are a family of marine fishes, commonly known as lumpsuckers or lumpfish, in the order Scorpaeniformes.

Cyclopteridae includes the following valid genera:[1] Lumpsuckers are named appropriately enough; their portly bodies are nearly spherical with generally drab coloration and lithic patterns.

Many species have bony, wart-like tubercles adorning the head and body; these are important taxonomic features of the family.

The simple, rounded fins are small with the exception of the broad, fan-like pectorals, which actually extend ventrally.

Before their yolk is completely absorbed, juvenile lumpsuckers consume the larvae of crustaceans, which grow on seaweed near the surface, and smaller halacarid mites.

[3] Hatchlings have well-developed pectoral fins and adhesive pelvic discs, which the fish use to cling to rocks in shallow water.
